TH ROTTLE-VALVE CONTROLLER.

SPECIFICATION forming part of Letters Patent No. 4GO,245, dated March 26, 1889.

Application filed May 11, 1888. Serial No. 273,624. (No model.)

To aZZ whom it may concern:

Be it known that I, GUSTAVE S. NEU, of the city, county, and State of New York, have invented certain new and useful Improvements in 'lhrottle-Valve Controllers, of which the following is a specification.

My present invention relates to improvements in automatic power-controllers of the kind of which those shown and described in two previous applications for patents-namely, No. 262,114, filed by me January 27, 1888, and allowed April 19, 1888, and No. 264,870, filed by me February 21, 1888-are examples. In each of these examples a main steam or other power regulating valve is arranged to be operated in one direction by a weight or spring and in the opposite direction by an auxiliary motor connected with a steam, water, gas, or other fluid-power supply and itself controlled by a self-acting power-supply valve in operative connection with the main-valveoperating devices, and catches are arranged to automatically engage and restrain both the main and secondary self-acting valves and to be disengaged therefrom by electric or mechanical tripping devices, the arrangement being such that when the main-valve-restraining catch is tripped the main valve will be automatically operated by its weight or spring in one direction, and when the secondaryvalve-restraining catch is tripped the secondary valve will act automatically to start the main-valveoperating motor, and thus return the main valve to the restraint of its catch, and at the end of the main valves movement will be itself returned from its connection therewith to the restraint of its catch, and the motor thus stopped.

The main objects of my present improvements are to provide simpler and more eflicient mechanism for properly working the secondary valve from the main-valve-operat ing devices and the main. valve from the fluidpower motor.

The invention consists of certain novel features of construction and combinations of parts, which will be hereinafter set forth in detail, and distinctly pointed outin the claims.

Reference is to be had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a side, partly sectional, elevation of an automatic power-valve controller embodying my present improvements arranged to be operated by electricity. Fig. 2 is an enlarged cross-sectional elevation of the same on the line .1; a, Fig. 1. Fig. 3 is an en larged sectional plan view of a part of the same on the line 1 1 Fig. 1. Fig. l is an enlarged sectional plan view of a part of the same on the line 2' .2, Fig. 1.

In the device thus illustrated to show clearly the manner in which my present invention may be carried into effect the main fluidpower-regulating valve A, having the operating-arm A, the forked lever I), for automatically engaging the valve-arm A, the catch E, for automatically engaging the lover I) and restraining the arm A, the vibratory electric tripping device F, for disengaging the catch E and releasing the arm A, the fluid-power motor M, for operating the valve A in opposition to its actuating weight or spring, the power-supply pipe L of the said motor, the vent-pipe M the motor-controlling valve Ii, its operating-lever Ii, the forked lever N, for automatically engaging the arm of the lever If, the catch N, for automatically engaging the lever N and restraining the secondary valve L, and the vibratory electric tripping device N for disengaging the catch X and releasing the secondary valve, are all arranged on a supporting-frame, A", to operate, in general, as shown and described in my previous application, N 202,11i, before referred to. In the present instance, however, the main-valve arm A is actuated by a weight, A which is adjustable on said arm, so that its effective force may be readily regulated as may be necessary. The piston-rod M of the fluidpower motor M is also extended above the valve-arm A, and the latter connected to the piston-rod )l' by a pendulous link, A", pivoted at its ends to the rod and valve-arm, respectively, so as to proptrly accommodate the rotary movement of the valve-arm A to the vertically-reciprocating movement of the piston-rod M Further, the motor-controlling valve l. is in this case a slide-valve of short travel, havin its stem I passed loosely through the valve-operating lever L, which is forked. to embrace the cylinder of the motel-M and pivoted on opposite sides thereto and provided with stops Z Z on opposite sides of said lever, so that when the arm of the lever If is swung into engagement with the forked lever N and catch N, as shown in full lines in Fig. l, the valve L will be moved to cut off the steam or other fluid from the motor M, and when the arm of the lever L is released by the action of its tripping device N and is swung downward to the position indicated in dotted lines in Fig.1, the valve L ill be moved to open the admission and close the exhaust, as particularly set forth in my pre vious application, No. 262,114, before mentioned.

The mechanism here shown for automatically operating the secondary valve L by the action of the main valve A, and embodying the principal feature of my present invention, may be described in detail as follows: An inflexible rod, S, is passed loosely through the arm of the secondary-valve-operatinglever I through a longitudinal slot, A formed in the main-valve arm A, and its upper end is mounted to slide lengthwise in a guide, S, fixed on the supporting-frame A". A coiled spring, S is placed on the rod S between the main-valve arm A and that of the secondary valve-operating lever L and the lower end of the spring attached to acollar, C adapted to bear upon the lever L and to be secured ad j ustably to the rod S by a set-screw, while the upper end of the spring is provided with a head, S adapted to be borne upon by the under side of the main-valve arm A. The

' adjustment and arrangement is such that when the main-valve arm A is released by its tripping device and is carried downward by its weight A to open or close the main valve, as the case may be, it compresses the spring S against the secondaryvalve lever-L*,wl1ich is, however, restrained by its catch N, and thus, when the secondary-valve lever L is released by the action of its tripping device N the tension of the compressed spring S will throw the lever L downward and cause the valve L to admit the steam or other fluid to the motor M and move the main-valve arm A in opposition to its weight A all substantially in the manner described in my second previous application, No. 264,870, above re ferred to.

On the operating-rod S, above the mainvalve arm A, is arranged loosely a second coiled spring, T, the lower end of which rests upon a bearing, T, mounted to slide lengthwise on the upper side of the valve-arm A, over the slot A therein, and having a tongue, T fitted to slide in said slot A without turn iug, so that the spring T will bear continually upon the arm A, while permitting the full play of the rod S in the slot A of the arm A as the same swings in its arc. On the rod S,

above the spring T, is fixed an adjustable stop, T against which the spring T is adapted to hear when the main-valve arm A is swung A catch, T is pivoted in a vertical upward.

slot, A, in the supporting-finme A, and is borne upon by a spring, T so that its nose T will be normally projected outward in the path of the stop T and will engage and lock the same with the rod S and secondary-valve lever Ij against movement, so that as the main-valve arm A is swung further upward, the spring T will be compressed between the same and the stop T", against which latter its tension will thus be exerted.

An angular tripper, T, is pivoted to the supportingframe A in such a manner that one arm, U, will project through the slot A therein into the path of the bearing T, carried by the main-valve arm A, and the other arm, U be adapted to bear upon the catch T while retained by a slot, U, therein, the adjustment and arrangement being such that just as the main-valve arm A is engaged and restrained by the forked lever D and catch E the bearing T thereon strikes, as a bearer, the arm of the tripper U, causing the arm U of the latter to press the catch T rearward, so that its nose T will be disengaged from the stop T, which, being released, will be forced upward by the tension of the compressed spring T, carrying with it the rod S. The latter is provided with a stop, V, on its lower end below the secondary-valve leverL which stop will bear upon the said valve-le ver and return the same to the restraint of its forked lever N and catch N, thereby stopping the motor M and automatically setting the whole apparatus in readiness to be operated again as before.

A guide, Y, projecting outward and downward from the face of the frame A, is arranged to receive and hold the main-valve arm A against lateral movement as it engages the angular tripper U. In the present instance the supporting-frame A is presumed to be of metal, and the ends of the main and secondary valve-operating arms A and If and the various parts of the electric locking and releasing devices to be insulated from the frame and from each other, as in part indicated; but this insulation maybe'avoided by using a frame wholly or partly of insulating material, as wood.

The electric circuit for operating themainvalve-working mechanism in this case is from the battery I through the wire I, the electro magnetic vibrator G, the wire 1 the spring contact-piece K, the forked lever D when in engagement with its catch, the wire I the circuit-closer J, whether automatic or hand, and the wire I to the battery I again, so that when the circuit-closer J completes the circuit the valve-arm A will be released and fall, at the same time breaking the main circuit through the lever D, which is, by preference, made with a curved arm, D, to co-operate by sliding contact with the contact-piece K, swinging out of engagement with said contact-piece K. The secondary-valve-operating circuit is from the battery-wire I by the wire II, through the electromagnetic vibrator N the wire 11, the spring contact-piece O, the

forked lever N, which, like the main forked lever D, has a curved contact-arm to co-oper ate by sliding contact with the spring contactpiece 0, the wire H the self-opening circuitcloser R, which is arranged to be closed by the descending main-valve arm A, as described in my first previous application, 202,114, but the lower eontact-piece of which is yielding instead of rigid, as in my said previous application, the wire 1-1, the circuitcloser Q, whether automatic or hand, and the wire H to the battery-wire 1 so that when the secondary circuit is completed by the circuitcloser Q, the secondary valve will operate first to start the motor H and return the main valve to the restraint of its catch, and then be automatically reset for operation, as also clearly described in my said previous appli cation, No. 262,114:.

This invention is also readily applicable to other operating devices whose action is similar to that of the main valve herein described.

I claim as new and desire to secure byLetters Patent 1. In a device of the character described, the combination, with the cylinder, piston, ports, and slide-valve of a fluid-power motor, of a forked lever, L", embracing the cylinder and pivoted on opposite sides thereto, the stem of the slide-valve working loosely through said lever and having stops Z Z 011 opposite sides thereof, substantially as described.
